Why mapping Used in Java

-
Basically Mapping will configure on xml because of following reason.

> When we use multiple file on different package then that time server doesn't decide which file we execute.

> on XML we define full controlling path . like if i click on ___ Control will forward to ___- page 

> On html form tag we define form action = --- so that is called xml and find where class has been define if find then perform operation else get error 


Hope this will help 
Thanks
